Abstract

A system and method in accordance with the present invention applies short bursts of a high temperature fluid to a hydrogen-loaded fiber (10) to relocate the hydrogen within the fiber in the proximity of the fiber’s core (120) - to achieve a fiber having significantly improved photosensitivity. A stronger fiber grating is realized when the fiber is subsequently exposed to ultraviolet light.
